I added $5 in credit and used Mudfish for only 5 days with Full VPN turned off, just to play World of Warcraft. I only had it running for about 3 hours on each of those days (during my raid times). The rest of the time I play without Mudfish. However, today I woke up and my balance is negative.
I configured everything exactly the same way as the other people I play with, and they all spent around $0.20 during the same period—only mine used up the entire $5. I don’t run anything in the background while playing, and even if I did, wasn’t Mudfish supposed to count only the game traffic?
Yesterday I noticed that my credit was running out, so I enabled the logs to try to identify the problem, but I can’t figure it out.
